About our fire rated sealant in Colworth

Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. If you have gaps filled with a product that isn’t fire-rated and sealant items on a fire risk assessment action list, we can help, whatever the surface.

Somewhere as small as Colworth, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

There’s a 12-month guarantee on every job, whatever its size.

Is Colworth within the area you cover?

Yes, Colworth is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

What information do you need?

The location, the problem and the rough size of the job. If you can, email a few photos.

How do I get a quote for fire rated sealant in Colworth?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote.

How long will you be here?

A typical job takes from a few hours to a few days, depending on the number of gaps and the access. Your quote will say how long we expect yours to take.

What fire rating will the seal have?

Ratings and certification sit with the product’s test evidence and whoever specified the work. We apply the specified product to the manufacturer’s details and list the locations and products for you.

Do you provide details of the products used?

Yes. When the job is done, we give you the locations and products. If you need pictures or a set layout, ask when you get a quote.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

How the visit works

There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes anything from a few hours to several days, depending on how many gaps there are from start to finish. In a small place like Colworth, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

Preparing for the visit

  • Tell us if parking is tricky
  • Tell us about any previous sealing or DIY attempts
  • Mention any sign-in or site rules at work premises

Getting a quote

Landlords, agents and businesses in Colworth

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

What we can’t put right

A few problems are outside what sealant work can do:

  • Fire risk assessments, which need a qualified assessor
  • Sign-off of the building, which sits with building control or your assessor
  • Big openings where sealant alone isn’t the tested solution

If in doubt, call 0345 464 0079 or send us an email and we will say what we think.

Surfaces we seal

  • Service penetrations
  • Plasterboard & masonry
  • Door frames
  • Flats & HMOs
  • Linear gaps
  • Pipe & cable gaps

Fire rated sealant in Colworth: local notes

For seaside hotels, guest houses and holiday lets around Colworth, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Managing a site like Bartons Primary School? Then fire-stopping around service openings should be restored whenever new services go in.

Leave it or put it right?

For some gaps, sealant isn’t the right answer and another system is needed. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. If a gap is not suitable for sealant, we will tell you. Around Colworth, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Take a look at what affects the cost or what customers say.

Can I do it myself?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

How to look after the new joints

To keep the joints looking good and working properly:

  • Keep general-purpose foam and caulk away from fire-stopping gaps
  • Look in service cupboards and ceiling voids from time to time
  • Ask every contractor to reseal any fire stopping they disturb
  • Don’t paint over fire sealant until it has cured

Don’t drill through or remove a fire seal without putting it back properly. New services through a sealed wall should include fire stopping in the plan.

When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.

Common problems we fix in Colworth

Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

Common reasons people contact us are:

  • Linear gaps at the head of walls
  • Seals cut through by electricians, plumbers or data installers
  • Joints picked up in a fire-stopping survey
  • Open gaps behind door architraves

Letting a property close to Bognor Regis station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
